Perhaps you should try some spelling variations:
"_ optimization algorithms" » "_ estimation algorithms", "_ estimation algorithm", "_ optimized algorithms"
"_ optimisation algorithm" » "_ estimation algorithm", "_ estimation algorithms"
"same optimized algorithm" » "same optimized algorithms", "same optimizer algorithms", "some optimized algorithm"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("same optimized algorithm") or ((("_ optimisation algorithm") OR ("_ optimization algorithms"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("same optimized algorithm") OR ((("_ optimisation algorithm") OR ("_ optimization algorithms")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"same optimized algorithm\") or (((\"_ optimisation algorithm\") OR (\"_ optimization algorithms\"))))".
• Removing quotes may allow a broader search: (( same optimized algorithm ) or ((( _ optimisation algorithm ) OR ( _ optimization algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("same optimized algorithm") or ((("_ optimisation algorithm") OR ("_ optimization algorithms"))))*.
